Genes affected

PRICKLE1 (HGNC:17019): (prickle planar cell polarity protein 1) This gene encodes a nuclear receptor that may be a negative regulator of the Wnt/beta-catenin signaling pathway. The encoded protein localizes to the nuclear membrane and has been implicated in the nuclear trafficking of the transcription repressors REST/NRSF and REST4. Mutations in this gene have been linked to progressive myoclonus epilepsy. Alternate splicing results in multiple transcript variants. A pseudogene of this gene is found on chromosome 3.

Uncertain significance, criteria provided, single submitter	clinical testing	Athena Diagnostics	May 08, 2017	- -
Uncertain significance, criteria provided, single submitter	clinical testing	Ambry Genetics	Mar 29, 2019	The p.R534Q variant (also known as c.1601G>A), located in coding exon 6 of the PRICKLE1 gene, results from a G to A substitution at nucleotide position 1601. The arginine at codon 534 is replaced by glutamine, an amino acid with highly similar properties. This nucleotide position is highly conserved in available vertebrate species. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -

This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 534 of the PRICKLE1 protein (p.Arg534Gln). This variant is present in population databases (rs756192425, gnomAD 0.06%). This variant has not been reported in the literature in individuals affected with PRICKLE1-related conditions. ClinVar contains an entry for this variant (Variation ID: 281207). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt PRICKLE1 protein function with a negative predictive value of 80%. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
